I had stopped at the Briley Show Room on the way to Eagle Lake , TX and ask them what choke to use for 3.5 steel T's. They told me to use the extended choke for steel and the I Mod for T's. This was prior to Ti chokes. 20 years later I am still using it.
Briley extended I MOD chokes were tested against other constrictions at our club in a series of informal test and were the only chokes that gave good patterns at 40 yards. Most of my friends from all parts of LA use them and shoot up to six flats of steel per year. No damage to guns or chokes and dead ducks.
